70.    The gyrfalcon, an Arctic birdof prey, has survived a close brush with extinction; its numbers are now five times greaterthan when the use of DDT was sharplyrestricted in the early 1970s.
(A)    extinction; its numbers are nowfive times greater than
(B)    extinction; its numbers are now five times more than
(C)    extinction, their numbers now fivefold what they were
(D)    extinction, now with fivefold the numbers they had
(E)    extinction, now with numbers five times greater than
想问问大家什么时候用greater than，什么时候用more than? 另外E选项的错在哪里呢？

Prep 12的一道语法题：
Which of the following most logically completes the passage?
Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much
below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving
them highly vulnerable to predators. In general, larger moths can fly faster than smaller ones and hence have a
better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why-
___________.
A. large moths are generally able to maneuver better in flight than smaller moths
B. large moths are proportionally much more common in warm climates than in cool climates
C. small moths are more likely than large moths to be effectively camouflaged while on vegetation
D. large moths typically have wings that are larger in proportion to their body size than smaller moths do
E. most predators of moths prey not only on several different species of moth but also on various species of other
insects

这里为什么C选项不对呢？正确选项是B

1. Greater than一般用在具体的数字比如 the number is greater than... More 一般用在具体的Noun, 比如More apple. 这里其实是比较的一种特殊平行形式，应该是its numbers are now five times greater than when the use of DDT was sharplyrestricted in the early 1970s. 是两个时间的对比
2.E选项的错误，RON的回答：if you're going to use "now" + some phrase as a modifier, then "now" must accurately modify the action and timeframe of the preceding clause.
e.g.
James is expanding the scope of his job search, now looking in Malaysia and Thailand as well as in Singapore
--> this sentence is correct, because "now looking in..." actually modifies (describes) the way in which james "is expanding his search".

here, now with numbers five times greater than does NOT modify the idea of "surviving a close brush with extinction"; instead, it is a much later situation, far removed from (and in considerable contrast to) the near-extinction. therefore, a modifier is inappropriate here; a separate clause, written in a different tense (as in the correct answer), is a better solution.
这里我个人觉得有个小TIP，就是在有别的选项能更清楚表达意思的时候，一般都不会选with，因为with的用法太多了
3 C选项不是说小M比大M更容易伪装，这个和前面的题干无关吧，B选项说因为大M最适温度高，所以温度较高的时候比例更大

likelihood是可能性，我们说的是可能性大/小，不是可能性多/少
